FINISH-REMOVER AND THE rnnraaeiirtonrnnnnor.

To all whom it may concern:

Be it known that I, CARLETON ELLIS, a citizen of the United States,and resident of Larchmont, Westchester county, New York,

, tion products, if desired, with the incorporation of suitable strong sulfuric or other acid material, the remaining ammonia or other acetate material neutralizing any acid tendency of'the chlorinated solvents. used.

Acetates, such as metallic acetates including potassium, ammonium, sodium, magnesium and barium acetates,'are quite soluble in methyl, ethyl and other alcohols and in other allied loosening finish solvent materials (that is, solvents of a generally alcoholic character or action in removers) such as the allied ketonic solvents, including methyl ethyl ketone, methyl acetone (that is, a composition containing about 40% of acetone, some wood alcohol and the balance higher ketones) and acetone. The solution i I may be readily effected bv heating the alcolil ijng metallic salt and acetic esters with the holic or similar solvent body in a reflux condenser in contact With an excessof the desired acetate or other salt capable of efi'ecting esterification, suitable amounts of acid material such as strong or anhydrous sul-' furic or hydrochloric acid being incorporated if desired, the temperature being carried up to near the boiling point of the solvents used, or, if desired, the solution may take place in a digester preferably in the presence of an excess of the acetate, the pressure and temperature being carriedup to any desired point to facilitate solution and the resulting esterification, although such increase oftemperature is not always necessary to effect the desired conversion of the solvent material. Under such conditions the alcohol and strong acid which may be slowly added in amounts nearly suflicient to completely combine with the base of the acetate used react to form the correspond Specification of Letters Patent?- Patented J 1 27 11915. Application filed July 18, 1908. Serial'No. 444,239.

alcohol or other solvents employed, such acetic or similar esteric solvents materially adding to.the finish softening and solvent actlon of the remover. Among other salts capable of effecting such esterification are other alcohol soluble salts preferably having organlc acid radicals of the fatty or arc matic series, such as formates, propionates, butvrates, and'so forth. An illustrative remover of this character may be formed by incorporating seven parts of calcined sodium acetate with nine parts of denatured alcohol and two parts of methyl ethyl lretone, four parts of strong sulfuric acid being slowly added so as to prevent the formation of ether's, the mixture being preferably stirred in a closed di'gester or mixer havlng agitating means therein which may be provided with a reflux condenser. The sulfuric acid added is nearly sufficient to neutrahze the base of the acetate'used so as to form'a considerable amount of acetic esters of the alcoholic and ketonic solvents, thus materially increasing their finish softening and solvent "properties. Eleven parts of carbon-tetrachlorid in which one partof parafiin or otherwaxy material may if desired be dissolved, may then be incorporated with the mixture and also four parts of crude terpineol or pine oil and one-half part of anhydrous ammoniumacetate which may of course be prepared by allowing dry am monia gas to percolate through glacial acetic acid. The particles of sodium sulfate formed are agglomerated with the colloidal waxy material and uniformly distributed by the continued agitation of the mixture so as to give a very desirable stiffening material throughout the body of the remover. The presence of ammonium acetate keeps the remover alkaline by the esteric action of such acetate material, thus having a valuable antacid action and effectually neutralizcapable of displacing the ammonia radical v and having such esteric action as has been indicated. Instead of the sodium acetate referred to an equivalent amount of potasalthough the more volatile and inflammable should only be used -in small proportion if.

the non-inflammable character of the remover is important.

acetylene for instance may also be used and may replace to some extent at least carbontetrachlorid in such removers as indicated.

Another illustrative remover may comprise nine parts of grain alcohol, one part of Wood alcohol, eleven parts of carbontetrachlorid, one part of ammonium acetate, one to three parts of amyl acetate Which -may be added in considerable quantity to such removers without materially increasing their infiammability, two parts of carbolic acid and one part of Wax. Another illustrative remover may comprise nine parts of denaturcdalcohol, one part of sodium acetate, one-half .part of ammonium chlorid, five parts of'carbon-tetrachlorid, five parts of cresylic acid, one part ofwaX, such as parafiin or ceresin, Which may be conveniently dissolved in carbon-tetrachlorid. Another illustrative remover may comprise twelve parts of denatured alcohol, one part of amyl alcohol, eleven parts of carbont,etrachlorid-, five parts of wood tar oil, one part of kerosene and one part of ammonium acetate which may be replaced if desired by one part of sodium acetate and one part of ammonium chlorid or sulphate. Another illustrative remover may comprise eleven parts of denatured alcohol, one part of sodium acetate, one part of ammonium chlorid, nine parts of carbon-tetrachlorid with which one part of paraffin may be dissolved if de- .sired.

The invention has been described in this case which contains subject-matter taken from United States patent application Other chlorinated finish solvent material, such as chlorinated 420,808, filed March 13, 1908 in connection with a number of illustrative ingredients, formulas, proportions and methods of preparation, to the details of which the invention is not of course to be limited.
